New K'NEX Ball Machine Element - Cooperating Arms (5-ball)

Hey everyone! I have finally finished my brand new 5-Ball element. I have been working on this for the last couple months and finally have the time to share it with you all. The machine measures about 4 x 4.5 x 7.5 (in blue rods). The machine needs an input of two balls to function. Thereby it outputs two balls, as they cycle through the machine.
If there is any problems, questions, suggestions ect. Let me know! I would love to help you out! :)
I hope you all like it!

The Frame














A Wall




Support for the Trapdoor Mechanism



Important! The purple connector should be in the exact same orientation as shown on the picture. There are two ways the 2 purple connectors can be clicked together, but in this case there is only one correct way. Otherwise the mechanism will not work properly I think. TIP: look at end of the white rods, and what parts are visible and what part isnt inside of the purple connector.
The Trapdoor Mechanism







In the fourth picture it is shown more clearly on how the purple connectors should be put together :)
A Railing


Support for the Push Mechanism


Entry Path to Trapdoor








Exit Path of the Trapdoor










Use dark blue 3D connectors here, I used the wrong color.
You don't have to ofcourse if you dont care about that sort of thing :p
Some Barriers






I dont have a clear picture of where to put the parts on the machine, but it will become more clear soon
The Rotating Bridge













The last picture kinda shows how to put the pieces together
I also dont have a picture of where to put it on the machine, oops ':D
The Lift Arm





The position of the yellow rods is really important!
The Push Arm








Connect the arm to the trapdoor via the blue rod!
A Doorframe

Having fun so far? Let me know in the comments below :)
The Doorframe Frame



A Path and Its Barrier







Notice the black Y-connectors at the bottom of the path!
An Arch



Notice it doesnt connect with green rods, it just sits on top of the yellow connectors
Also, don't forget the black Y-connector, there is just one of them, this is an important piece
Finishing Touch


Important!!!

Try out the trapdoor/push arm mechanism now, if there are any problems, its easier to fix them now! It requires two balls to work! If it doesnt work, try to reduce as much friction as you can, or else look back to see what went wrong.
More Framework


A Smooth Corner







The Counterweight for the Second Push Mechanism




The Middle Wall

Be sure you don't miss anything!
The Pusher





Connect it to the wall you just made, as shown in the final picture
Even More Framework







This part is finally finished now, add it to the machine! :)
Be sure to double check if every single rod is connected!
Connect the pusher to the counterweight with the blue rod!
Another Middle Wall



Be sure you dont miss anything!
The orange connectors at the top mights seem odd (first picture). Its just a regular 2-way orange connector, with two "clips with angled end 3D" into the side of it. One at the bottom and one at the top!
Positive Stop for Arm


I only used the red piece on the left for the red color :)
The Lower Arm








Connect the arm to the rotating bridge at, using the red rod (as shown in the final picture)
A Wall Extention


The Upper Arm





Connect this arm to the lower arm with the blue rod (as shown in the final picture)
Ps:
R.I.P. fingers...
Im sorry :p
This Little Thing


No name for this one
A Giant Wall and a Path




Make sure to connect every single rod, especially on the inside of the machine. The ones from the liftarm n such.
I know its a pain to connect this one, but I didnt know how to do it otherwise.
Also, be sure to connect the little path to the main machine.
Transition Path


It doesnt connect at the end, only at the front!
Finishing Touch


The blue connector in the top left will be chaned to a red connector later on. To prevent any confusion :)
The First Entry Path



Some Extra's




The red connector is visible in the second picture (look back at the previous step if you are confused :)
Wall 9000


How many wall does this thing have!?
Transition Path






The blue spacer is important here!
A Second Transition Path






A note about the red part in the second picture:
This ensures a smooth transition, but I noticed the balls are too quick sometimes. If this happens, remove this piece entirely!
Entry Path


The Lever





Note, the two blue rods can be changed out for a red rod. I chose an orange one, but thats purely for aesthetics.
The Final Framework :)


Release Mechanism










Try to reduce as much friction as you can with this part.
DONE!

The machine uses 5 balls, put 4 balls on the machine as shown in this picture. Put the final one on the top orange lever, and watch your machine go!
Notice: the machine outputs two balls and requires an input of two balls to function
Thats about it! Thanks for building and have a great time with your new element <3
